If there were other planets, one or more, that might be habitable for humans but with many difficulties, and not so heavenly as Earth (in comparison), would you decide to go rather than stay on a decaying and perhaps overcrowded Earth - given that travelling to such wouldn't take up all your life getting there (technology advancing to do this)?
